1. The cost of 4 hates is $29.68. What is the unit price?
OlgaM077 [116]

To find the unit price, divide the total price by the number of items. A unit price is a unit rate for one item.

1. 29.68 / 4 = 7.42

So $7.42 is the unit price.

2. 625 / 6 = 104 (rounded to the nearest whole number)

So Jess can type 104 words per minute.

30 points for anyone that can help please?
statuscvo [17]

Answer:

A) 1.5

B) x^2-23x+42 = (x-2)(x-21)

C) x=2, x=21

Step-by-step explanation:

a) 15 -2x / 3 = 4

15-2x = 12  (Times by three on both sides)

-2x = -3

x = -3/-2 = 3/2 = 1.5

b) x^2-23x+42

x^2-23x+42 = (x-2)(x-21)

c) x^2 -23x +42 = 0

x=2, x=21

(x-2) = 0  ⇒  x = 2

(x-21) = 0  ⇒  x = 21
